Subject: Fixes various warnings emitted in lib by the SunPRO cc compiler, and
X-Git-Tag: SQUID_3_0_PRE1~1357
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a76e35b13e9a0bc4ef02d4f1b336f4a96ec5b28c;p=thirdparty%2Fsquid.git

Fixes various warnings emitted in lib by the SunPRO cc compiler, and
synchronized the MD5 prototypes with OpenSSL.

* MD5 operates on binary data, not characters. Avoid signed/unsigned issues
* The bswap16/32 macros was not signed/unsigned safe
* lib/rfc2617 had several spurious extra ;
* MD5Final wants an unsigned char *
